[silk] Youtube an .pk Telecom

2008-02-25 Thread Gautam John
http://news.bbc.co.uk/1/hi/technology/7262071.stm

The BBC News website's technology editor, Darren Waters, says that to
block Pakistan's citizens from accessing YouTube it is believed
Pakistan Telecom hijacked the web server address of the popular
video site.

Those details were then passed on to the country's internet service
providers so that anyone in Pakistan attempting to go to YouTube was
instead re-directed to a different address.

But the details of the hijack were leaked out into the wider
internet from PCCW and as a result YouTube was mistakenly blocked by
internet service providers around the world.

What does that mean and is it that trivial to knock a site off-line?

...Pakistan Telecom routed the address block that YouTube's servers
are into a black hole as a simple measure to filter access to the
service. However, this routing information escaped from Pakistan
Telecom to its ISP PCCW in Hong Kong, which propagated the route to
the rest of the world. So any packets for YouTube would end up in
Pakistan Telecom's black hole instead.

What the heck does this stuff mean? It escaped? So anyone can 'escape'
routing information to shut down the 'tubes?

 as a dyed-in-the-wool Tambram (Tamizh Brahmin) Mami, I find this

 long as it is all in the abstract. Discussing *themselves* or people

That said, as far as 'discussion' goes, that stems from the dont ask

I find people unwilling to even question what they teach or learn themselves. 
When I learn carnatic music, I ask the meaning of the song in the language 
(usually telugu, tamil, kannada, malyalam, sanskrit which i am curious about) 
taught or why a particular raga is constructed in that way, how and why its 
similar or not, comparison with Hindustani music, and a zillion other mundane 
questions; which has always always annoyed every teacher i've known till date. 
Not that this research interests me but its just sheer curiosity; which i 
satisfy via the Internet. Maybe folks are not interested, dont care about the 
meaning or construction but I find the attitude toward teaching/learning more 
disappointing than anything else.

That's been the attitude of quite a few teachers. Science, maths, English or 
whatever. I was lucky to have some very good English teachers, and managed to 
flunk + bare pass my way through the rest of my subjects, leaving me with an 
abiding distaste for both science and maths.  And a lot of affection for 
English literature.

Oh well.. if that were different I would be reading sciam rather than Sir

Well, for a chronology of what went on, take a look at this -

http://www.renesys.com/blog/2008/02/pakistan_hijacks_youtube_1.shtml

Or for a simpler overview, see Brian Krebs' article in the Washington post
(in his securityfix blog) -
http://blog.washingtonpost.com/securityfix/2008/02/pakistan_censorship_order
_take.html

My comment there on that blog post might put it into simpler terms. For
something more complex, please get some cisco / other routing classes. Those
who are already CCIEs and reading this, please forgive me for a really bad
and oversimplified analogy



What this is like, is someone in a phone company in Atlanta screwing up and
announcing that everything in (say) the 781 area code belongs to his
telephone exchange, and is routed out of Atlanta rather than out of Boston
(which is where 781 is).

And then that Atlanta phone company sends out an update so that several
other phone companies actually believe it.

So, calls for boston people with 781 area codes end up getting rerouted to
Atlanta instead of Boston. And either getting lost in thin air (as theres
nobody in Atlanta who has a 781 area code phone) or making random unrelated
phones ring.

Its a crude analogy and phone switching doesnt really work this way .. but
thought I would try at least making one.

 In essence, yes. Sometimes. This piece may be of help:

In essence - yes, but most providers that provide connectivity (transit etc)
- have best practices that include filtering route announcements for sanity
checks, to make sure stuff like this just doesn't happen.

I mean, even if a big dumb 3rd world telco (like these guys, or like some of
our own homegrown ISPs) screw up router announcements, these are caught and
filtered out so that this damage doesn't occur

Unfortunately - PCCW (big hong kong ISP - pacific century cyberworks) that
provides connectivity to lots of smaller asian ISPs - doesn't do this.  And
youtube suffered as a result.

What pccw did to stop this happening was even dumber, they cut off all of
Pakistan telecom for a few hours.

As a completely irrelevant addendum to your explanation:

in the above context, I take a deep and unholy delight in the fact 
that Atalanta's area code is 404. (as in, document not found)
